C445UM Fault and Event Diagnostics

Faults: When a fault occurs, the FAULT LED will light and a
notification screen will provide fault description and access
to fault diagnostics. Users can view the trip snapshot or fault
queue right from the fault screen.

Inhibits: An inhibit is a condition that occurs while stopped
that will prevent starting. This could be a fault condition or a
parameter change that requires soft reset or creates
configuration conflicts.
When an inhibit occurs, the stopped LED flashes and an
Inhibit screen provides the reason. If an Inhibit is due to
parameter changes requiring soft reset, the notification
screen will provide a button to soft reset. If inhibit is due to a
configuration problem, a button option provides details about
the problem.

The FLT screen can be cleared by pressing OK, but the
FAULT LED remains lit. Clear a fault by pressing RESET.
A failed reset attempt is indicated by a blinking FAULT LED.
This means the reset command was received by the device
but the fault cannot be cleared because the condition is
still present.
The active fault can also always be viewed via PRG R Faults
and Events R Active Fault
Inhibit notification screens will not appear within the PRG
menu as the user may be changing multiple parameters and
will only want to Soft Reset once. The screen will appear if
the user takes any of the following actions:
1. Returns to the home monitoring screen by pressing
MODE/BACK. Pressing MODE/BACK once steps out of
each menu while pressing and holding will go
immediately back to home.
2. Press the START button
3. Lets the idle timeout expire with "Return to Home
Screen" enabled in timeout behavior (User Interface
Settings)
